How to Choose the Best Process Calibrators
Safety and Certification
Ensure any calibrator you consider meets relevant safety standards (e.g., ATEX for hazardous environments) and carries appropriate certifications. Proper calibration and maintenance of the calibrator itself are also crucial for maintaining its accuracy and reliability over time. Always refer to the manufacturer's specifications and user manual for detailed information on operation and safety.
Frequently Asked Questions
What is a process calibrator used for?
A process calibrator is used to measure, generate, and simulate electrical and physical signals. Its primary purpose is to verify and adjust the accuracy of instruments like transmitters, controllers, and indicators in industrial processes.
What types of signals can most calibrators measure or generate?
Most process calibrators can measure and generate standard industrial signals such as voltage, current (mA), resistance, and temperature (using RTD or thermocouple inputs). Some advanced models also handle frequency or pressure signals.
Is HART communication important?
Yes, HART (Highway Addressable Remote Transducer) communication is crucial for calibrating modern smart transmitters. It allows for two-way digital communication alongside the analog signal, enabling advanced configuration and diagnostics.
How do I choose between a handheld and a benchtop calibrator?
Handheld calibrators are ideal for field service and general-purpose calibration due to their portability. Benchtop models are better suited for laboratory environments where higher accuracy, more complex functions, and dedicated workspace are needed.
What does 'accuracy' mean for a calibrator?
Accuracy refers to how close the calibrator's output or measurement is to the true value. It's usually expressed as a percentage of reading plus a fixed offset, and higher accuracy means more precise calibration results.
